Ejection system for evacuating dangerous object from an aircraft in flight

Abstract

The invention comprises:
a system of evacuation comprising box including two doors, the first one giving towards the interior and the other giving towards outside of the aircraft.
The two doors are perfectly tight and the opening of one can be made only if the other is locked and conversely. This prohibition of opening is carried out mechanically
a container in which is inserted the dangerous object or supposed like such, and whose dimensions are such as the container can be introduced into the system of ejection. The container is closed by a tight door.
The container is equipped with a standard beacon GPS whose activation is done automatically when the dangerous object is introduced into the container. This beacon enables to localize the container after its ejection.
a system to immobilise the container in the ejection system in order to avoid any inopportune movement of the container in normal operation. This system is erased for introducing the dangerous object into the container and during the ejection phase.
a system of armament allowing simultaneously to lock the interior door, to unbolt the external door, to erase the device immobilizing the container in the system of ejection and to authorise the triggering of the ejection phase by pressurisation of the ejection system.
a system of pressurisation including a gas cartridge under pressure equipped with a device authorizing by a manual action the perforation of the gas cartridge associated with a a delivery system of gas towards the ejection system.
Moreover the conceived system following the invention has the following characteristics:
it can be used by duly trained crew
it is preferentially placed out of immediate sight of the passengers
it can be designed to ensure the ejection of objects of different sizes (small objects up to size and weight of standard cabin luggage)
it does not disturb the flying conditions
Its implementation can be done to avoid interfering with the structures of the aircraft
the container can be easily equipped with a GPS beacon (tracability)
it can be conceived to have an high level of security in its operation
it can be conceived to have a minor impact in term of weight penalty

SUMMARY OF THE INVENTION

The invention relates to an ejection system for evacuating dangerous object or supposed like
such, discovered on board aircraft (cabin) in flight.

The invention comprises:

- a system of evacuation comprising box including two doors, the first one giving towards
the interior and the other giving towards outside of the aircraft.

The two doors are perfectly tight and the opening of one can be made only if the other is
locked and conversely. This prohibition of opening is carried out mechanically

- a container in which is inserted the dangerous object or supposed like such, and whose
dimensions are such as the container can be introduced into the system of ejection. The
container is closed by a tight door.
The container is equipped with a standard beacon GPS whose activation is done

automatically when the dangerous object is introduced into the container. This beacon
enables to localize the container after its ejection.

- a system to immobilise the container in the ejection system in order to avoid any
inopportune movement of the container in normal operation. This system is erased for
introducing the dangerous object into the container and during the ejection phase.

- a system of armament allowing simultaneously to lock the interior door, to unbolt the
external door, to erase the device immobilizing the container in the system of ejection and to

authorise the triggering of the ejection phase by pressurisation of the ejection system.

- a system of pressurisation including a gas cartridge under pressure equipped with a device
authorizing by a manual action the perforation of the gas cartridge associated with a delivery
system of gas towards the ejection system.

Moreover the conceived system following the invention has the following characteristics:

- it can be used by duly trained crew

- it is preferentially placed out of immediate sight of the passengers

- it can be designed to ensure the ejection of objects of different sizes (small objects up

to size and weight of standard cabin luggage)

- it does not disturb the flying conditions

- Its implementation can be done to avoid interfering with the structures of the aircraft

- the container can be easily equipped with a GPS beacon (tracability)

- it can be conceived to have an high level of security in its operation

- it can be conceived to have a minor impact in term of weight penalty
